Note that this is as of 3-28-21 , stuff may change like prices.
1. Head to the Seneschal in town - hold alt to find them. They seem to be out of the way.
2. Buy a License - right now the merchant is by far the best deal requires for you to sell each item at 200 to break even. Basic and advanced requires each item to be sold for more to break even.
3. Go to trader and open the regular trade menu. Click on the left arrow of the item you want to sell to set the price. You can click the arrow multiple times if you have multiple of the item. Hit done after 2 or three items as the shop does reset which will undo your work if done wasn't pressed.
4. Talk to the merchant again for the dialogue to get your money.
